To all whom it may concern:

Be it known that we, ERNEST ENGEL and EMMA Ronnnrs, citizens of the United States, residing at La Moure and Edmunds, respectively, in the counties of La Moure and Stutsman and State of North Dakota, have invented certain new and useful Improvements in Journal-Lubricators, of which the following is a specification.

This invention relates to an improved journal lubricator for cars and has as its primary object to provide an arrangement wherein the journal will continually run in oil without the use of the commonly employed waste as a packing for the journal and wherein a fresh supply of oil will be continuously furnishedto the journal to effectually overcome any possibility of the heating thereof.

The invention has as a further object and more specifically to provide a device of this character employing a lubricant or oil receiving pan to be held to the journal so that the journal will run through the lubricant within the said pan and wherein an endless carrier will be provided for continuously pumping or transmitting a fresh supply of oil to the pan as the journal rotates.

And the invention has as a still further object to provide an arrangement wherein any slack in the carrier may be adjustably taken up and to also provide an arrangement wherein the said carrier will be yieldably tensioned to travel with the journal as the journal is rotated.

Other and incidental objects will appear as the description proceeds and in the drawings wherein we have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views,

Fig. 4 is a plan View showing the pan detached with the carrier guard illustrated in section, this view particularly showing the troughs leading from the terminals of the guard into the pan for directing lubricant from the guard to the pan.

In order that the construction and operation of our improved lubricator may be accurately understood, we have illustrated in the drawings, a conventional type of journal box or casing 10 provided with a door 11 and operatively receiving the journal 12 of a car axle 13. As is usual, the journal 12 is provided, at its outer extremity with an annular radial flange or shoulder 14 and fitted over the journal is a cap bearing 15.

Coming now more particularly to the subject of the present invention, a lubricant pan is employed having side walls 16, a bottom wall 17 which preferably slopes downwardly from opposite ends of the pan to deepen the pan, and an end wall 18 with the opposite end of the pan closed by a bearing block 19 mounted between the said side walls. Arranged within the pan adjacent the extremity thereof opposite the block 19, is a similar block 20, these blocks 19 and 20 being cut away to fit against the journal 12 while the end wall 18 which is outwardly spaced from the shoulder 14 of the journal is similarlycut away to receive a corrugated pulley or sprocket 21 seating against and connected to the adjacent end of the journal 12 by spaced bolts or other suitable fastening devices 22. At its outer end, the pulley 21 is formed with a radial flange 23.

Arranged beneath the pan adjacent opposite sides thereof are pairs of longitudinally extendingreversely directed bowed springs 24 with the springs of each pair connected at a point substantially midway the ends thereof, as particularly shown in Figs. 1 and 2, by a rivet or other suitable fastening device. The lowermost springs of thesaid pairs are arranged to seat at their extremities against the bottom wall of the casing or box 10 while the uppermost springs freely engage at their extremities with the bottom wall 17 of the pan adjacent the ends thereof for yieldably supporting the pan beneath the journal 12 and holding the bearing blocks 19 and 20 of the pan against the said journal with the journal extending within the pan.

Extending outwardly beyond the pulley 12 from the side walls 16 of the pan, are oppositely disposed wings 25 preferably integral with the said side walls and pro jecting from the pan adjacent the upper margin thereof. Extending inwardly between the wings 25. are angle members 26 cooperating with the said wings to provide channel shaped shoulders or ledges with the upstanding walls of the said members each bent to form inwardly directed longitudinally extending flanges 27. The. ledges 26 are arranged to slope downwardly from the outer extremities thereof in the direction of the pan and mounted upon the said ledges, is an arcuate lubricant guard or shield 28 extending over the pulley 21 in spaced relation thereto. This shield, at its extremities, is formed with inwardly directed channel members 29 slidably fitting within the channels provided by the angle members or ledges 2'6 with the free upstanding walls of the said channel members forming flanges 30 'interfitting with the flanges 27 for detachably connecting the guard with the pan. The channel members 29 being received upon the inwardly and downwardly slop ing ledges 26, are inclined in the direction of' the pan and the said channel members, at their inner extremities, are formed with reduced inwardly directed troughs or gutters 31 inclining downwardly and inwardly to project at their inner extremities into the pan adjacent the side walls thereof. The gutters 31 are preferably integral with the channel members 29 and the body of the guard 25 and the inner side walls of the sai'd gutters, at the inner ends of the said channel members, are'provided with openings or gates 32 forthe'channel members arranged over the pan at the adjacent extremity thereof. I

It will now be observed that the outer extremities of the lowermost springs of the pairs of springs 24 are arranged to extend outwardly beneath the pulley 21 and connected to the adjacent terminals of the said springsand extending transversely therebetween isa channel jrnember 33 The side walls of this channehme'mber are formed with longitudinally spaced openings for recelving plns 34' upon whlch are mounted rollers35." Trained around the said rollers to extend over the pulley 21 for engagement with the corrugated face thereof, is a sprocket chain or lubricant carrier 36 held against displacement from thepulley by the I flange 23.

all times maintained full of oil and being yieldably held in operative relation with respect to the journal by the springs 24, the said journal will constantly run in the the oil within the panto be maintained effectually lubricated. Furthermore, so longas the journal 12 is rotated, the carrier 36 will continuously actto replenish the oil as it is used or consumed from the pan to at all times maintain thevpan full. Any possibility of the heating of the journal is thus overcome. p

The guard 28 is arranged tocatch any oil flying from the carrier 36 as the said carrier travels about .the pulley 21. Oil upon the inner face of the said ,guard'will tend to run down the guard into the channel members 29. thereof. These channel members being inwardly inclined will then-dirrect such oil inwardly toward the gates '32 as well as into the gutters 31 to fall within 7 the adjacent end of the pan to thus contribute in supplying the pan with oil.

As will be best observed upon reference to Fig. 3 of the drawings, the pins 34: may

be adjustably positioned within the: open ings in the side walls of the channel member 23 for adjustably spacing, the rollers 35 laterally with respect to each other and consequent-1y taking up anyslack in the chain or carrier 36. These rollers are preferably so arranged with respect to each other that the said carrier will normally pull upwardly thereon against the tension of the lowermost of thesprings 2e.- These'lowermost springs will, therefore, also act to-yiel'dably hold the carrier in engagement with the working face of the pulley 21 so that the said carrier will, at all times, mo ve with the pulley upon the rotation of theournal 12.

It will therefore be Seen that we provide a particularly efficient construction for the purpose set forth and a lubricator which will dispense with the use of the commonly employed waste-as a packing for thejournal while, at the same time, the device may be to rotate with the journal and actively enreadily employed in connection with rolling gaging the carrier for operating the carrier upon the rotation of the journal with the said pan disposed to receive lubricant deposited upon the said means by the said carrier, and means for supporting the pan in active position with respect to the journal with the said last mentioned means engaging the carrier for tensioning the carrier about the said first mentioned means.
